Old Shimano Calais, old Tour PT Quantum are a pain to take apart. Tatula TW reels especially the original are more complicated than others. I’ve done so many D n E Curados and Gen 1-2 Revos I can assemble them easily even from a pile of parts. High end spinners like a Stella or Certate have tons of washers and shims to keep track of. The ABU spinners that come apart from the rear are horrible. I could go on all night. Lol
